What does it mean when singers harmonize?
Harmonization happens when musical notes combine into one chord often in thirds or sixths, and then into chord progressions1. ... In rock or pop music, a backup singer will harmonize with the lead singer by adjusting the pitch of her note based on the lead singer's pitch so that they are in tune.
How do you learn ear harmonies?
To get started creating harmonies by ear is to sing along with melodies that are already familiar. Ideally, these would be unaccompanied simple songs, though that is not absolutely necessary. Find recordings of kid's songs, traditional melodies, holiday favorites, or hymns.
